Evaluation of the ultrasonic transducer electrical matching performance

Abstract

Performance of electrical matching of an ultrasonic transducer to the excitation generator is analyzed. The analysis is based on a transducer measured impedance. Real power supplied to the ultrasonic transducer is one of evaluation criteria. The obtainable bandwidth as well as it’s product with a real power supplied are assigned as the alternative performance evaluation criteria. Effective bandwidth is adopted from radiolocation as one of criteria. Most popular matching circuits are analyzed using the mentioned criteria. Algorithms for matching network selection are presented.
